I was trying to fit the Ducati Soft Bag side racks with the H&B tubular rear rack on my 2018 DS just last night after seeing your old setup @Gestalt but couldn’t get a clean fit on the left or right side. I went back to just the rear rack with soft saddle bags. It does seem possible with just a little hole enlarging, angle grinding, and maybe some longer screws. Do you remember if you had to modify the rear rack or the side racks? I can get pics showing the non-fit next time I’m at the shop. I’d love to find a solution.
